"One has but to observe a community of beavers at work in a stream to understand the loss in his sagacity, balance, co-operation, competence, and purpose which Man has suffered since he rose up on his hind legs. He began to chatter and he developed Reason, Thought, and Imagination, qualities which would get the smartest group of rabbits or orioles in the world into inextricable trouble overnight."
